Being a billionaire is an impressive achievement. But, what's more impressive is being both a billionaire and a Christian at the same time. It has been repeated over and over again in the Bible that money is the root of all evil, which makes these Christian billionaires all the more inspiring. Learn who these people are, what they own, and how the Christian faith helps them deal with success.

Owner and founder of Hobby Lobby, Green is the largest evangelical benefactor in the world. According to Forbes, he has already given more than $500 million to religious causes as of 2012.

Green has always been outspoken about his faith. In an interview with Forbes, he said "So I have learned to say, 'Look, this is yours, God. It's all yours. I'm going to give it to you.' " In the same interview, he also said that 90 percent of his company will go to the ministry if the company undergoes a sale or dissolution. Further, he also sponsors the YouVersion Bible app, which is free to download.
